Application led April 25, 1927. Serial No. 188,318.

This invention relates to shut-olf valves and is designed for useprimarily in plumbing fixtures, such as faucets and the like, and theobject is to produce an all metal 'faucet which can be operated easily.and quickly and which shall -efliciently guard against the escape orleakage of Water up through the cap of the faucet. A further object isto produce a shut-off valve mechanism of the charactermentioned which isof simple, strong, durable and inexpensive construction. A still furtherobject is t produce a valve in which wear of the operative parts shallbe taken up automatically for the purpose of guarding against escape ofwater up through the cap of the valve.

With the objectsmentioned in view, the invention consists in certainnovel and useful features of construction and combinations of parts ashereinafter described and claimed;v

and in order that it may be fully understood,- reference is to be had tothe accompanying in which:

Figure 1 is a central vertical longitudinal section of a faucetequippedwith a valve embodying the invention, a tubular plugof thefaucet being broken away to indicate thatgits vexternal threads arereversed with res ect to its internal threads.

igure 2 is a horizontal section on the line 'II- II of Figure 1. I

Figure 3 is a horizontal section on the line III-III of `Figure 1.

Referring to the drawing in detail, 1 indicates a faucet provided with aperforated partition 2 dividing the faucet into a passage 3 forreceiving water from the service pipes (not shown), and a dischargespout 4.

The faucet is provided with the customupwardly-projecting cylindricalbody portion 5-which is internally and rexternally threaded, theinternal .threads being adapted lfor engagement by a tubular threadedplug 6, the bore of said plug being an upper threaded portion 7,-thethread being of the box or square type by preference,and a lower smootportion of slightly greater diameter and providing a downwardly-facingvalve seat at its lowerA end in communication, when the vvalve is openas hereinafter explained, with chamber y or passage 3. It will be notedthat the plug 6 bears yupon the partition 2, and the meeting faces ofsaid partition and plug provlde a ground jointimpervious -to the passageof water. The lower portion of the plug 1s `the cap, by

divided ,imoy

4profvided with an external circumferential groove 8 providing a chamberin communication with the spout 4, and the wall of the grooved portionis formed with a pluralit lof openings 9, through which water, a

mitted to the enlarged or lower portion of the bore ofthe plug when thevalve is open, may enter the groove 8 and pass freely therefrom throughthe spout.

A cap 10 is screwed upon the external threads of the'cylindrical bodyportion 5 of the faucet, and is provided with a downwardly-facinginternal shoulder 11 and above the same with an upwardly-taperingorconical passage 12. A conical'plug I4 lits in the socket 12 and isprovided'a't its lower end with an outwardly-projecting flange 15 heldnormally adjacentthe shoulderh 11 of a spring 16 interposed between theconlcal plug and the` upper end of the body portion 4 of the faucet, thesaid plug being provided with a stem 17 projecting upwardly throu'ghlthe cap.

The said plug is provided with an angular socket 18 receiving a`correspondingly contoured sleeve 19 pinned as at 20 upon the upper endof the valve stem 21, said-stem extending through the bore of the plu 6and being equipped at its lower'end with a spherical head 22 forengagingthe valve seat -at `the lower end of plug 6, with a watertight relation.The stem is provided with a thread 23 engaging the corresponding thread7 'of plug 6, the external threads o the plug 6 and the threads of thestem 21 being reversed sothat the'operation of the stem shall have notendency to' turn the plug, and the lower endof the sleeve 19 and theopposing portion of-the uppel` end of plug 6 are preferably correspongly bevelled, so that when the valve 1s full'y opened, said portionsshall engage with a; watertight joint and thus prevent water enteri thecap. In this connection it will be no that the pressure of .the spring16 upon the bottom of the cone holds .the latter at all times seatedwith a water-tight joint on the conical bore o f the ca and hengguardsagainst the leakage o water at any-.time through the top of the cafwhereas the water-tight joint established tween the top of the plug 6and the lower end of the sleeve 19, occurs only when the valve is fullyopened, and at such time prevents water entering the cap. A double guardis thus provided against escape of water from the Y top of the cap as isso frequently encountered with the conventional forms of faucets, aftera comparatively short period of service.

A handle 24 of any suitable design or type is mounted upon ,the stem 17where it projects from the top of the cap, and is secured rigidly uponsaid stem in the conventional manner indicated or in any other suitablemanner.

When the valve is closed, the head 22 is in engagement with the valveseat at the lower end of plug 6, as shown, and to open the valve thehandle is turned in the proper direction. This results in rotating theconical plug, and said plug in turn imparts rotation to the valve stem,andthe latter due to the fact that it bears a threaded relation to plug6, moves downwardly and unseats the valve. During this operation watermay work up around the threaded stem into the cap but cannot escapebecause of the watertight relation between the cone` and cap. Theunseating movement of the valve is limf ited or arrested by theengagement of the `lower end of the sleeve with .the opposing surface ofthe plug 6, which engagement, as

hereinbefore stated, establishes an nter mediate water-tight joint whichprevents water from entering the cap at all, so that water admitted tothe enlarged portion of the bore of plug 6, must pass off through thespout, with none of it spurting up into or through the cap. With afaucet of this character, the repeated engagements of the valve withsits seat and of the sleeve with the upper end ofthe plug, will resultin making the joints more perfect, and in the event wear develops whichwould impair these joints it will be taken up automatically, as aslightly increased range of movement of the handle in one direction willbringstheyvalve tightly toits seat and in the reverse direction willbring the sleeve tightly down on plug 6, it being also# noted that thespring 16 which is of considerable. strength and under considerabletension, will always maintain the cone in water-tight 'relation with theconical socket or passage of the cap.

From the above description, it will be apparent that I have produced avalve mechanism for faucets which embodies the features of advantage setforth as desirable in the statement ofthe objects of the invention, and`while I have illustrated the preferred construction, it is to beunderstood that changes may be made in the form and proportion of theparts and in other respects Vwithout departing from the principle ofcon-l struction and mode of operation involved or from the spirit andscope of the appended claims.
